The purpose of this study was to analysis and identify the impacts of striped snakehead (Channa striata Bloch) fish farming in net cages on socio economic and environmental aspects. This study was a survey research. Location determination in Bangkau Village, Hulu Sungai Selatan Regency, South Kalimantan Province, Indonesia was done purposively because this area was a center for cultivating striped snakeheads in Hulu Sungai Selatan Regency. The collection of respondent data in this village was carried out in a census of 20 people from the whole population of cultivated striped snakeheads in net cages. The effect on social was done by identifying the effect of social aspect, the economic aspect determined by analysis used was the calculation of profit (π) and payback period (PP), while the environmental aspects, it was done by identifying the measurement of water quality. The results showed that from the social aspect, this business influenced the use of labor in its business, benefits obtained from the business of cultivating this striped snakeheads varied between 627,433.33 IDR to 9,789,533.33 IDR per year, while the payback period was 2.23 years. This cultivation effort from the environmental aspects of water quality is still within the class 3 water quality classification tolerance limit.

Quality Assessments

Lake water is important to all life and surroundings with multiples benefits and forms either in natural or man-made conditions. One of the most well-known tools for assessing the water quality is Water Quality Index (WQI) and widely used including Malaysia. Lake water quality should be represented in lucid way like other surface water regarding to the WQI standards for water quality assessment on lakes. This paper aims to review on lake water quality classification and its uses based on WQI standards in Malaysia. In this review, the uses of WQI for assessing the lake water and functioned of lakes are discussed. Results on pH from 5.0 to 9.2, BOD in mg/l from 0 to 180, COD in mg/l from 5 to 150, SS in mg/l from o to 1800, DO in mg/l from 0 to 8 and AN in mg/l N from -1 to 26. Variety of numbers is due to different loading of pollutions and location. With used of WQI on lake water quality assessments, further action can be taken for the uses on water resources by maintaining the quality. It also will broaden the uses of lake water as alternative of water resources in Malaysia.

The purpose of this study was to identify the business problems of cultivating striped snakeheads (Channa striata Bloch) in embedded net cages, analyze the feasibility of the business of cultivating striped snakeheads in net cages and identify the assumptions/perspectives of the impacts of striped snakehead farming in embedded net cages on environmental aspects. This study was survey research. Location determination in Bangkau Village, Kandangan Subdistrict was done purposively because this area was a center for cultivating striped snakeheads in Hulu Sungai Selatan Regency. The collection of respondent data in this village was carried out in a census of 20 people from the whole population of cultivated striped snakeheads in embedded net cages. The identification of problems that occurred in the business of cultivating striped snakeheads in embedded net cages was done by descriptive analysis in the field. The analysis used was the calculation analyze business feasibility used the analysis of Net Present Value (NPV), Net Benefit Cost Ratio (Net BCR) and Internal Rate Return (IRR), while to know the effect on environmental aspects, it was done by identifying and analyzing the description of population rescue. The results showed that the farmers’ problems were the lack of availability of seeds, the fluctuations in the selling price of fish and domestic fish, which could be attacked by scabies. The business of cultivating striped snakeheads in embedded net cages in Bangkau Village, Kandangan Subdistrict, Hulu Sungai Selatan Regency was feasible to be carried out in accordance with the results of analysis namely Net Present Value 4,943,337, Net Benefit Cost Ratio (Net BCR) 2.29 and Internal Rate Return (IRR ) amounting to 51.53%. This effort influences the assumption of rescuing striped snakehead fish populations from this cultivation is 48.75%.
